A process From my personal experience, the best way to work in a team was when we were using Scrum. I have no experience with Extreme Programming or Kanban, though, so I can't tell you which one is "best". As noted above, the best is determined by your team composition, not by objective parameters. For me Scrum was best for two main reasons.
